REPAIR PART FOR SCRAERS.

Application ined Deem'ber ie, 1921i. yserial No. 755,516.

To all whom t may concern:L

Be it known that Evnicn'r'r S. Hrioip oook, a citizen ofthe United States, residing at Richn'iond, in the county of Henrico and State of Virginia, have inventedl certain new and useful Improvements in Re-` pair Parts for TWheel Scrapers, of which the following is a specification.

Inv the use'of wheel Scrapers of the construction wherein the scraper pan is supported from the axle on the ends of a bail or fork pivoted to a bracket on the iii-le the constant strain and wear results in bre-alage of the arins of the bail at points alljacent to the fulcruin or point of attachment to the axle. The repair of such parts by the usual methods necessitates either welding a new extension to the arin of the bail which isbrokeinor the substitution ofjan entirely new bail, both of which methods are comparatively expensive. The purpose of my invention is to provide means for repairing such bails or forks in an expeditious y f and comparatively inexpensive manner. lr. carrying outv this purpose, I provide a repair part which can be readily united with tliel'iroken arm of the bail in such a manner v necessary) and said part is then driven on f over the end of said arm 11 until the apen' as to restore its original efficiency and by a method that can be practced by anyone `of ordinary mechanical skill even where 'a blacksmith is not available. p

Referring to the drawings which are made a part hereof and on which similar reference characters indicate similar parts, l

Figure 1 is aside elevation of a scraper showing `my repairpart in use thereon;

Figure 2, a section on the dotted line 2-2 of Figure 1, and

Figure 8, a detail perspective of the attachment. `In said drawings the portions marked A representl the axle of the wheel scraper, B the draft pole, andV C the scraper pan, all of which parts are or may be of the usual or any approved construction and arrangement and require no `detailed Adescription herein.

The axle is bent to forni a pair of nprights 10 located one adjacent to the wheel spindles on each end thereof and said axle pivots in the wheel boxes as usual. The arms of the bail 11 are secured to uprights 10 by bolts or avyoke 12. y

When oneof the arms ofthe bail'll becomes worn lor broken 'it is cut off by use of a cold-chisel, or other means. at a point' 18 and an extension is then provided by means of my repair part let, now to be described.

Said repair partk consists of a bar having a socket 15 formed on one end adapted to receive the end of the bar 11 preferably af-V ter it is heated so that it will become slightly7 malleable and 'permit said socket to be driven thereon. Said part 14 is providedwith apertures 16 to receive thebolts 12 forvsecuring the bar to the uprights 10.y The outer end of said repair part 14 extends forward to the saine point as the original length of the i broken arm of the fork or bail 11, and isy provided with an aperture 17 through which pivot bolts 1S extend, to which the forward end of the scraper pan C is hung by means of links 19 and an aperture 2O through which passes a bolt 21 to ywhich the draftpole 'B is connected. f

In applying said repair part, the broken arm is cut off, as before stated, yand the end of the part 14: carrying the socket 15 is then preferably `heated by any `means available until it vis in a somewhat malleable condition (although this may not always be found tures for the bolts 12 register with the apertures in the bracket 10 and in the end of said arm 11, and the bolts 12 are adjusted in place, thus making a very rigid and secure connectionbet-ween sa d part '14` and the' broken arm ,'11, and constituting an extension vthereof which completely restores the original utility of said arm as well as its strength and operative etiiciency. means the repair of the broken part is facilitatedand the operation of the machine interrupted for only a comparatively short spaceof time and the necessity of taking such machine to a blacksmitlrshop yfor repair is obviated. i i i l-Iaving thus fully described my said invention, what Iclaini as new and desire to secure by Letters Patent, is: y

1. In a wheel scraper a repar part for the supporting bail for the scraper pan coin-r substantially as set forth.

By this 2. A repair part for the scraper pan supporting-j baii of wheel Scrapers eomprising, d body having a longitudinally dispose opening therethrough adapted to receive one ends of a' huil arm said hody at one ede of said opening having un extension of suhstantially the. Width of the opening and hoing oset in alinenlent with said opening' to form a. continuation of Said haii arm when inserted in said Socket, said offset portion being of'K a oonguration corresponding to the forward portion of the bai] arm, sulstentialiy as set forth.

.In Witness whereof, I have hereunto ser ny hand und seal at VnShlngton, Dlstriot of Columba; this lth day of November,
